According to one embodiment, the first door-open request information and the second door-open request information may have different data formats but include the same detailed information.

For example, when the first door-open request information contains door security information generated in a Bluetooth communication data format, the sub-reader 2000 may acquire the second door-open request information in a magnetic communication data format containing the door security information.

According to one embodiment, the sub-reader 2000 may perform user authentication on the basis of the detailed information included in the first door-open request information and acquire the second door-open request information when the user authentication result indicates that the user is a valid user.

The sub-reader 2000 may perform user authentication on the basis of the first door-open request information.

According to one embodiment, when reference authentication information corresponding to the authentication information included in the acquired first door-open request information has been pre-stored in the sub-reader storage unit 2400, the sub-reader 2000 may determine that the user is a valid user.

The reference authentication information may be authentication information that is pre-registered and stored for a valid user. For example, the reference authentication information may be biometric information of a valid user.

According to one embodiment, when an authentication token included in the first door-open request information holds authority for opening the door corresponding to the sub-reader 2000, and/or the door operating device 1000, the sub-reader 2000 may determine that the user is a valid user.

The sub-reader 2000 may acquire the second door-open request information when the user authentication result indicates that the user is a valid user.

When the user authentication result indicates that the user is a valid user, the sub-reader 2000 may acquire the second door-open request information in the second data format so that the second door-open request information may include detailed information which indicates that the user is a valid user. The detailed information indicating that the user is a valid user may not be limited to information that indicates that the user is determined to be a valid user by the user authentication, and may be replaced with information that requests opening of the door.

According to one embodiment, the sub-reader 2000 may acquire the second door-open request information on the basis of door security information, which is pre-stored on the basis of the first door-open request information.

When the first door-open request information only contains data necessary for user authentication, the sub-reader 2000 may perform user authentication on the basis of the first door-open request information and acquire the second door-open request information on the basis of door security information pre-stored in the sub-reader 2000 when the user authentication result indicates that the user is a valid user.

For example, when the first door-open request information obtained by the sub-reader 2000 is biometric information, the sub-reader 2000 may perform user authentication on the basis of the biometric information and obtain the door security information pre-stored in the sub-reader storage unit as the second door-open request information when the user authentication result indicates that the user is a valid user.

When the pre-stored door security information is formed in a data format different from the second data format, the sub-reader 2000 may acquire the second door-open request information by converting the security door information into the second data format.

According to one embodiment, the second door-open request information may be transmitted (S120).

The sub-reader 2000 may transmit the second door-open request information. The sub-reader 2000 may provide the second door-open request information to the door reader 1100 through the second sub-reader communication unit 2120.

For example, the sub-reader 2000 may provide the second door-open request information to the door reader 1100 through a magnetic secure transmission method. Accordingly, when the door reader 1100 is a magnetic reader, the door reader 1100 may obtain the second door-open request information from the second sub-reader communication unit 2120 using a magnetic communication method.

The door reader 1100 may provide the obtained second door-open request information to the door control unit 1700 and the door control unit 1700 may determine whether to open or close the door when the door security information is obtained from the door key 4000, and may control the door to be opened or closed on the basis of the determined result.
